getSize(Entry entry,

Called before writeTo to ascertain the length in bytes of
the serialized form of t.

boolean

isReadable(java.lang.Class<?> type,

java.lang.annotation.Annotation[] annotations,
MediaType mediaType)
Ascertain if the MessageBodyReader can produce an instance of a particular type.

genericType - the type of object to be produced. E.g. if the
message body is to be converted into a method parameter, this will be
the formal type of the method parameter as returned by
Class.getGenericParameterTypes.

annotations - an array of the annotations on the declaration of the
artifact that will be initialized with the produced instance. E.g. if the
message body is to be converted into a method parameter, this will be
the annotations on that parameter returned by
Class.getParameterAnnotations.

mediaType - the media type of the HTTP entity.

httpHeaders - the read-only HTTP headers associated with HTTP entity.

entityStream - the InputStream of the HTTP entity. The
caller is responsible for ensuring that the input stream ends when the
entity has been consumed. The implementation should not close the input stream.

Returns:

the type that was read from the stream.

Throws:

java.io.IOException - if an IO error arises

WebApplicationException - if a specific
HTTP error response needs to be produced. Only effective if thrown prior
to the response being committed.

genericType - the type of object to be written, obtained either
by reflection of a resource method return type or via inspection
of the returned instance. GenericEntity
provides a way to specify this information at runtime.

annotations - an array of the annotations on the resource
method that returns the object.

Write a type to an HTTP response. The response header map is mutable
but any changes must be made before writing to the output stream since
the headers will be flushed prior to writing the response body.
